Abstract

Economic pressure and increasing environmental awareness stimulate the development of new taxi operation technologies and procedures. One of the most promising developments is the use of electrically powered landing gears for medium-sized aircraft in civil aviation. Meeting the prerequisite that the weight of the new equipment and the weight of the saved fuel are approximately balanced, operational as well as economic and environmental benefits can be achieved. This paper describes a method how to assess these benefits by means of a fast-time simulation model and presents the findings for two airports. The first, Frankfurt am Main Airport (FRA), is one of the major European hub airports. Due to the higher share of heavy aircraft, which are assumed not to be equipped with an electric taxi system, the relative benefit of almost 20% fuel savings is lower than at the second airport in the study, Berlin Brandenburg Willy Brandt Airport (BER), which is still under construction and estimated to open in 2014 at the earliest. As the share of medium-sized aircraft is expected to be higher, relative fuel savings of more than 36% can be achieved there. Besides these economic and environmental impacts, operational benefits can also be observed as the aircraft can back out from their parking stands autonomously. By this, the time-consuming coupling and decoupling of a pushback vehicle can be eliminated.
